Ingredients
- 2 boneless, skinless chicken breasts
- Salt and pepper to taste
- 1 tablespoon olive oil
- 1 avocado, sliced
- 4 slices of cheese (Swiss, cheddar, or provolone work well)
- 4 slices of bread (sourdough, ciabatta, or your choice)
- 2 tablespoons mayonnaise
- 1 tablespoon Dijon mustard
- 1 small red onion, thinly sliced
- 1 tomato, sliced
- Butter or olive oil for grilling the sandwiches
Instructions
Step 1: Prepare the Chicken
Start by seasoning the chicken breasts with salt and pepper on both sides. This ensures that the chicken has a good base flavor. Heat a skillet over medium-high heat and add the olive oil. Once the oil is hot, place the chicken breasts in the skillet and cook for about six to seven minutes on each side. The chicken is fully cooked when it reaches an internal temperature of 165°F and has no pink in the center. If you do not have a meat thermometer, cut into the thickest part of the chicken to check that it is white all the way through. Once done, remove from the skillet and let it rest for a few minutes before slicing it thinly.
Step 2: Prepare the Avocado and Cheese
While the chicken is resting, slice the avocado. Make sure it is ripe but not overly soft. A ripe avocado should give slightly when pressed but should not feel mushy. If you have difficulty slicing it, cut it in half, remove the pit, and then scoop out the flesh with a spoon before slicing. Prepare the cheese slices and set them aside.
Step 3: Prepare the Bread
Lay out the bread slices on a clean surface. Spread a thin layer of mayonnaise and Dijon mustard on each slice. This adds a tangy and creamy element that enhances the overall flavor. If you prefer a different spread, you can use butter or even hummus for a different twist.
Step 4: Assemble the Sandwiches
On two slices of bread, layer the sliced chicken evenly. Add the avocado slices on top of the chicken, followed by the cheese. Place a few slices of red onion and tomato on top. If you are adding extra ingredients like greens or hot sauce, now is the time to include them.
Place the remaining slices of bread on top, making sure that the mayo side is facing down. This helps the bread achieve a golden, crispy texture when grilled.
Step 5: Grill the Sandwiches
Heat a skillet or grill pan over medium heat. Add a small amount of butter or olive oil to the pan. Place the sandwiches in the skillet and cook for about three to four minutes on each side, or until the bread is golden brown and crispy and the cheese is melted. Press down gently with a spatula to help everything heat evenly. If you have a panini press, you can use it instead for an even crispier result.
Step 6: Serve and Enjoy
Once the sandwiches are done, remove them from the skillet and let them cool for a minute before slicing them in half. This prevents the cheese and fillings from spilling out too quickly. Serve warm and enjoy.
Notes
Common Troubleshooting Advice:
- If the chicken is browning too quickly but is not fully cooked inside, lower the heat and cover the skillet to allow it to cook through.
- If the bread is getting too dark before the cheese melts, reduce the heat and cover the pan briefly to let the cheese soften.
- If the avocado is too firm, let it sit at room temperature for a day or two to ripen. You can speed up the process by placing it in a paper bag with a banana.
Helpful Kitchen Tips:
- To speed up meal prep, cook the chicken ahead of time and store it in the refrigerator. You can use leftover grilled or roasted chicken as well.
- To make slicing avocado easier, use a butter knife rather than a sharp knife to avoid accidents.
- If you do not have a skillet, you can toast the sandwich in an oven at 375°F for about 10 minutes, flipping once halfway through.
